方式一
@WebServlet(name = "FirstServlet",urlPatterns = "/first")
public class ServletOne extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("ServletOne!");
}
}启动类
//Springboot启动项注解
@SpringBootApplication
//自动扫描Servlet注解
@ServletComponentScan
public class ServletAppOne {
public static void main(String[] args){
SpringApplication.run(ServletAppOne.class,args);
}
}运行结果
方式二
public class ServletTwo extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("ServletTwo!");
}
}启动类
//Springboot启动项注解
@SpringBootApplication
public class ServletAppTwo {
public static void main(String[] args){
SpringApplication.run(ServletAppTwo.class,args);
}
//自动扫描获取servlet对象
@Bean
public ServletRegistrationBean getServletRegistrationBean(){
ServletRegistrationBean bean = new ServletRegistrationBean(new ServletTwo());
bean.addUrlMappings("/second");
return bean;
}
}运行结果
spring boot 进行文件上传
@RestController
public class FileUpLoadController {
//处理文件上传
@RequestMapping("/fileUploadController")
public Map<String, Object> fileUpload(MultipartFile filename)throws Exception{
System.out.println(filename.getOriginalFilename());
//设置文件上传的路径
filename.transferTo(new File("f:/"+filename.getOriginalFilename()));
//定义map
Map<String, Object> map = new HashMap<>();
//返回提示信息
map.put("msg", "ok");
return map;
}
}测试html页：
<body>
<form action="fileUploadController" method="post" enctype="multipart/form-data">
上传文件：<input type="file" name="filename"><br/>
<input type="submit"/>
</form>
</body>亲测有效！
spring boot 访问静态资源
1. resources目录下的static文件夹
2. src\main目录下的webapp文件夹
好记性不如烂笔头！
